Aerie Bra Size Chart & Sizing
Young, unretouched, and one of the friendlier mall ranges: soft contour bras and bralettes, numbered and alpha.
Aerie in numbers
Aerie's real-body marketing made it the default first bra brand for a generation. Its numbered Real Sunnie and Real Happy lines are lightly padded contour bras in mainstream sizes; its bralettes are alpha-sized.
Your measured size in Aerie
How this is computed: your US size read straight onto the US label, then adjusted for how Aerie typically grades: true bands, true cups.
Where Aerie sits on the size grid
Cups A–DDD (G in select styles). Not every band–cup combination exists; the largest cups usually appear on mid-range bands only.

Aerie labels in United States notation. Rows are bands (US number, US equivalent in brackets); columns are cup letters as Aerie writes them. Each cell links to that size's guide.
| Band | A | B | C | D | DD | DDD |
|---|---|---|---|---|---|---|
| 30 (US 30) | 30A | 30B | 30C | 30D | 30DD | 30DDD |
| 32 (US 32) | 32A | 32B | 32C | 32D | 32DD | 32DDD |
| 34 (US 34) | 34A | 34B | 34C | 34D | 34DD | 34DDD |
| 36 (US 36) | 36A | 36B | 36C | 36D | 36DD | 36DDD |
| 38 (US 38) | 38A | 38B | 38C | 38D | 38DD | 38DDD |
| 40 (US 40) | 40A | 40B | 40C | 40D | 40DD | 40DDD |
| 42 (US 42) | 42A | 42B | 42C | 42D | 42DD | 42DDD |
Coverage is approximate to the brand's core collections; the largest cups typically exist on mid-range bands only. US DDD is written DDD here.
Does Aerie run small or big?
Aerie bands run true to size across US bands 30–42: start with your measured band on the loosest hook, and expect it to feel snug for the first week if you are coming from an add-inches size.
Aerie cups grade true to the measured difference from A to DDD: a gap or overflow in the measured letter is a shape signal, so change the cut before the size.
Aerie wires are average width for the US system. Straps: Standard.
